# Design.markdown

## Profile (per speaker)
An **open-source, plain-text specification format** introduced by Google. Describes design tokens, typography scales, and component rules in a format easily readable by AI models, aiming to become an industry standard.

## Role in This Source
The centerpiece of Google's interoperability bet — see [[concept-google-stitch-and-markdown]] and [[claim-google-stitch-strategy]]. Read by [[entity-product-google-stitch]] before generation.

## ⚠️ Validation Caveat
No canonical evidence of a 'Design.markdown' standard from Google. Real adjacent artifacts include:
- **Material Design Tokens** (JSON-based, m3.material.io)
- **Material Theme Builder** outputs

The speaker may be describing an emerging or pre-launch initiative, or conflating Google's token-based design system tooling with a Markdown-shaped spec. The *strategic intent* (open, AI-readable design system format) is real even if the named SKU is not.
